URL as a string and values in Xcode - ios

Question

I am working on a web service app and i have a question. I am calling a specific Url site with the following code:
NSURL *Url = [NSURL URLWithString:[requestStream stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
NSString *htmlString = [NSString stringWithContentsOfURL:Url encoding:NSUTF8StringEncoding error:&error];
Then i create an nsstring and print it with the NSLog and i got the following results:
2014-05-14 15:50:58.118 jsonTest[1541:907] Data : Array
(
[url] => http://sheetmusicdb.net:8000/hnInKleinenGruppen
[encoding] => MP3
[callsign] => SheetMusicDB.net - J
[websiteurl] =>
)
My question in how can i parse the URL link and then use it as a value? I tried to put them to an array or a dictionary but i get error back. So if anyone can help me i would appreciate it.
Ok i managed to grab the link with the following code:
if(htmlString) {
//NSLog(#"HTML %#", htmlString);
NSRange r = [htmlString rangeOfString:#"=>"];
if (r.location != NSNotFound) {
NSRange r1 = [htmlString rangeOfString:#"[encoding]"];
if (r1.location != NSNotFound) {
if (r1.location > r.location) {
_streamTitle = [htmlString substringWithRange:NSMakeRange(NSMaxRange(r), r1.location - NSMaxRange(r))];
NSLog(#"Title %#", _streamTitle);
}
}
}
} else {
NSLog(#"Error %#", error);
}
Thank you for your suggestions. My problem now is that i pass the string into an avplayer and i can't hear music.

Answer 1

I think this will be help for you..
// #property (nonatomic,retain) NSMutableData *responseData;
// #synthesize responseData;
NSString *urlString=#"http:your urls";
self.responseData=[NSMutableData data];
NSURLConnection *connection=[[NSURLConnection alloc]initWithRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:urlString]] delegate:self];
NSLog(#"connection====%#",connection);
JSON Delegates :
-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
[self.responseData setLength:0];
}
-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[self.responseData appendData:data];
}
-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
self.responseData=nil;
}
-(void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSArray *response_Array = [NSJSONSerialization JSONObjectWithData:self.responseData options:kNilOptions error:nil];
// Write code for retrieve data according to your Key.
}

Try This:
NSString *urlStr=[NSString stringWithFormat:#"uRL"];
NSMutableURLRequest *theRequest=[NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlStr] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self];
[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;
if (theConnection)
{
receivedData=[[NSMutableData data] retain] ;
}
#pragma mark - Connection Delegate
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data{
// append the new data to the receivedData
// receivedData is declared as a method instance elsewhere
//NSLog(#"data %#",data);
[receivedData appendData:data];
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error {
// release the connection, and the data object
// [connection release];
// [receivedData release];
UIAlertView *prompt = [[UIAlertView alloc] initWithTitle:#"Connection Failed" message:[error localizedDescription]delegate:self cancelButtonTitle:#"Ok" otherButtonTitles:nil, nil];
[prompt show];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection {
NSString *content = [[NSString alloc] initWithBytes:[receivedData bytes]
length:[receivedData length] encoding: NSUTF8StringEncoding];
NSData *jsonData = [content dataUsingEncoding:NSUTF32BigEndianStringEncoding];
NSDictionary *jsonDictionary = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:nil];
}
}
